Hi,
I experienced the “dip” around my 4th week of treatment. It felt like what I call a “hurricane” of depression (rather than just a wave) and lasted about a week. Towards the end of the treatment (the past few weeks), I definitely relate to how you’ve been feeling. I had the same experience and considered quitting my job and TMS. I’ve gotten past it a little bit, but it’s still been emotional.
As for other anxiety, I don’t know about other people’s experiences, but getting used to post-treatment has caused me a lot of stress, which made me really anxious.
Don’t get me wrong, it feels amazing to not have to fight just to get out of bed anymore, but it’s something I’ve never felt before, so it’s taking some time to adjust.
